NUT-LOCK- SPEGIFIGATION forming part of Letters Patent No. 762,107, dated June 7, 1904. Application filed January 30, 1903, Serial No- 14l,162. (N0 model.)

Be it known that l, ALBERT MONROE VVIL- SON, a citizen of the United States, and a resident of Cherokee, in the county of Cherokee and State of Iowa, have invented a new and Improved Nut-Lock, of which the following is a full, clear, ,and exact description.

This invention relates to a nut-lock especially adapted for use. at rail-joints and in analogous structures where two nuts are adjacent to each other and to devices of that class in which a connecting piece or shank extends between the two nuts, each end of the shank carrying a lock proper working with the respective nuts.

This specification is an exact description of one example of the invention, while the claim defines the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view showing the invention in use. Fig. 2 is a plan view illus trating the two nuts by dotted lines, and Fig. i) is; an enlarged perspective view of the nut- 0 indicates the body or shank of the device, each end of which is formed with a hook I) and the shank or body a passing diametrically between these hooks so as to connect with opposite sides thereof. These parts are formed, preferably, of a piece of sheet metal and may be made by cutting or stamping the same so that the two hooks b and the shank a lie in the same plane, thus'placing the strain edgewise on the sheet metal. This construction provides for great strength and at the same time enables a relatively slight amount of material to be used, thus much reducing the cost of the look. A portion of the bill c of each hook b is turned up out of the plane in which the hooks b and the shank a lie, so as to engage, preferably, the sides of the nut and form a positive lock, as the dotted lines in Fig. 2 indicate. It will benoted also that the inner edge of each bill c is straight and that the said edge intersects with the corresponding edge of the hook substantially at right angles, thus insuring an engagement or abutment against one of the faces of the nut for the full extent of the said inner edge of the portion of the bill which may be turned outwardly for such purpose. The hooks Z) are elongated in the direction of the length of'the device, and this allows for a full adjustment of the device on the boltsthat is to say, if measurements be erroneous and the lock does not accurately fit the bolts this elongation of the hooks will allow the longi tudinal adjustment of the lock with respect to the bolts without interfering with the action of the bills 0 on the nuts.

In applying the device if the bills are to engage the sides of the nuts the lock should first be placed over the bolts and then the nuts screwed up onto the lock. Finally, the

. bills of the hooks 6 should be bent up alongside of the nuts to engage the same and securely lock the nuts in-place.

It will be observed that this device being stamped from a single sheet of metal may be produced at very slight cost, since all necessary strength is gotten from the disposition of the metal so that it will take the strain edgewise, and this disposition allows the lock to be made from a relatively small amount of material. Further, after the parts are in place and the bills bent up as described a positive and secure lock is formed.

Various changes in the form, proportions, and minor details of this invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intent of my claims.

By constructing each of the hooks b elongated, as explained, a substantially elongated recess is formed between the inner edge thereof and the adjacent edge portion of the body or shank a from which said hook is turned, and in this way provision is had by which the looking device may be successfully applied to two bolts having nuts-thereon, which may vary in size or width, it being understood, as already suggested, that the bills 0 are not bent to engage the nuts until the latter have been screwed up tightly on the bolts. The device may also be similarly employed in a successful manner in instances of variation of spread of the bolts with reference to each other, and thus will the advantage possessed by my device be apparent over others of its kind, which, so far as I am aware, are necessarily completed prior to the application of either the device itself or the nuts. The nearest approximation to my device hitherto devised consists of a bar which is formed with end loops to surround the bolts of a set, the sides of the loops, however, being originally constructed to fit the bolts and permitting no accommodation of the device either to bolts which have spread nor to nuts of varying sizes, and, moreover, it is necessary to heat this bar to properly construct the device. Another device has also been hitherto devised employing also a bar having loops constructed to accurately fit the bolts, as in the first instance mentioned, the ends of the loops being made thinner to give them elasticity enough to spring into place after'the nuts have been screwed home on the bolts; but in neither of the instances furnished is the device capable of being used in the manner and for the same purposes as my improved device, as will be apparent.

Having thus described my invention, I claim as new and desire to secure byLetters Patent A double nut-lock comprising a body or shank of sheet metal, provided at opposite sides of the ends thereof with hooks forming with the shanks elongated recesses, for the application of the device to two bolts, the bills of the hooks forming one side of said recesses and having straight inner edges, the said bills being adapted to be bent flatwise to engage the said straight inner edges with faces of nuts screwed upon the bolts.

In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.

ALBERT MONROE WILSON.
